problems with refund

we currently have the rain 5g pakage that comes with the router. we recently relocated and now in an area where there is no 5g. we were not aware of this so we made a payment of R 699 on the 14/04/2022. I contacted support and they told me there is no coverage for our area. so im trying to figure out what do we do next...now we have to downgrade to 4g and get our own router. thats not a problem. but now we want a refund for the payment we made. and they said we paid for February, which was 2 months ago? and doesnt make sense to me??? where do we go from here? not getting much help.
